Three employees of the Warren County School System Food Service Department received an invitation from First Lady Michelle Obama to attend a reception at the White House. The invitation came as a result of West Elementary and Bobby Ray being awarded a Silver Certificate for their participation in a United States Department of Agriculture program called HealthierUS School Challenge.The recognition fit in with the first lady’s Let’s Move! initiative, which is what generated the invitation, according to school nutrition supervisor Jean Wix, who was one of the three, along with Melissa Livesay, food service specialist, and Ann Frye, cafeteria manager at West.The group attended a speech by the first lady on her concerns about childhood obesity.“It was the trip of a lifetime,” said Wix. “I felt very honored our program would be recognized for the work we’re doing.
